Yes, you can absolutely grow sage in an outdoor plant box! Sage (Salvia officinalis) is a hardy perennial herb that thrives in well-draining soil and full sunlight, making it an excellent choice for container gardening. Here’s how to ensure success:

1. Choose the Right Plant Box: Opt for a box with drainage holes to prevent waterlogging. A depth of at least 8-12 inches allows roots to spread comfortably.

2. Soil Requirements: Use a lightweight, well-draining potting mix with added perlite or sand to mimic sage’s native Mediterranean conditions.

3. Sunlight: Sage loves full sun—aim for 6-8 hours of direct sunlight daily. Place the box in a sunny spot like a balcony or patio.

4. Watering: Water sparingly, allowing the soil to dry between sessions. Overwatering can lead to root rot.

5. Pruning & Care: Trim regularly to encourage bushier growth and prevent legginess. Harvest leaves as needed for culinary use.

With minimal care, your outdoor sage plant will flourish, adding aromatic foliage to your garden and flavor to your dishes!
